What is atherosclerosis?

Atherosclerosis refers to the buildup of fats, cholesterol, and other substances in and on the artery walls, leading to reduced blood flow through the arteries. It is characterized by the hardening and narrowing of the arteries as a result of plaque buildup.

Option B describes a common misconception that relates to aging. While it is true that arteries can become less elastic and pliable as part of the aging process, atherosclerosis itself is not merely a normal physiologic process but rather a specific pathological condition that can be influenced by factors such as diet, physical activity, and overall health. The condition significantly affects cardiovascular health and can lead to serious complications, including heart attacks and strokes.

Understanding atherosclerosis is important for recognizing risk factors and implementing preventive measures in fitness and health programs. Maintaining an active lifestyle and a balanced diet can help mitigate the risks associated with this condition.
